Gate drivers are discrete parts and aren't integrated into microcontorllers because they require high voltages (12/24V vs 3.3V) amongst many other reasons. They also have to be located close to the IGBT and the designers would want it as a separate part because it gives them enormous flexibility. You aren't saving much by adding a gate driver to a micro and I can't think of any micro that has it integrated. There are simple things like motor drivers, etc. that may have a gate driver integrated but that's not a micro and those are also built on large nodes -- much larger than nodes used for microcontrollers. FWIW: I design advanced node (20-5nm) ASICs for a living, and have designed on older nodes before. I've also worked in power electronics.
